Our story for Woods Hole Oceanographic Institution’s Oceanus magazine on biologist Don Anderson’s field studies on harmful algal blooms, also known as “red tide.” Using the Cape Cod National Seashore’s Nauset Marsh as a mesocosm for understanding a global public health risk, the lab is using innovative remote technologies to identify and predict red tides, locally and on a global scale.
